About

Hi, I’m Anatolii Hamarko, a frontend engineer with 4+ years building production-ready interfaces for communication platforms, analytics dashboards, and enterprise web apps. I specialise in performance-minded Vue 3 and React ecosystems, design system rollouts, and real-time experiences secured with end-to-end encryption. I ship across Web, iOS, and Android from Figma concepts to Ionic/Capacitor builds.

I lead cross-platform delivery, building reusable UI libraries (100+ Vue components, 25+ composables) and marketing sites tuned for Lighthouse targets. I work with WebSockets, WebRTC, FFmpeg.wasm, and Jitsi Meet SDK to enable real-time messaging and media, while keeping bundle health, accessibility, and Core Web Vitals KPIs front and center. I’ve collaborated with Stripe, OneSignal, and Sentry in security-conscious, performance-driven projects.
